Most of us can look into our crystal balls and see that a handful of tech trends which became big in 2013 will probably get bigger next year: cloud computing, big data, the rise of tablets, the Internet of Things.

But market research firm IDC has gone one better by predicting how these trends will unfold next year — and generate billions of dollars.

People and companies will spend $2.1 trillion on technology

Worldwide IT spending will grow 5% next year to $2.1 trillion, IDC says.

People and companies will buy smartphones and tablets, a market expected to grow by 15% over 2013. Companies will also beef up their data centers with new hardware that works better with mobile devices. They’ll need servers, storage, networks, software, and services.

The only thing they won’t be buying more of is PCs. Worldwide revenues for PCs will be decline 6% in 2014, IDC predicts.

Countries outside the U.S. and Europe will buy tech like crazy

People and companies in emerging countries will buy new tech at a blinding rate in 2014.

The four hottest emerging markets, Brazil, Russia, India And China (often called BRIC), will up their spending by 13%, IDC predicts, with China leading the way.

IDC also predicts that, for the first time, other emerging countries will collectively start spending big on tech. This includes other countries in Asia, Latin America, the Middle East, and Africa.

All told, tech spending outside of the U.S. and Europe will rise 10% to nearly $740 billion and make up more than 1/3 of all worldwide IT spending. This will be where big IT vendors get most of – over 60% – of their growth.

Business will pour money into the cloud

2013 was the year that companies stopped kicking the tires on cloud computing, and started buying it big time. In 2014 spending on the cloud will be mind boggling.

IDC predicts that the cloud will drive $100 billion worth of spending in 2014, up 25% over 2013. That includes the hardware cloud service providers will need buy to keep up with customer demand.
